In the chain hoists , the sales volume is at least a large tonnage chain hoists . In over a long period of time have been very few sales of large tonnage , many manufacturers were on hoists on large-tonnage production is also on the sidelines, the market prospects for large tonnage many manufacturers lose confidence in chain hoists . On chain hoists industry, identification of the product is low , the smaller the scope of the product, coupled with the recent development of micro electric hoist , lifting many small operations can also be used flexibly . Chain hoists lifting tonnage that can achieve the same electric hoist , electric hoist to facilitate people are more willing to use the hoist . Then for large tonnage of chain hoists , chain hoists large tonnage generally refers to the weight of 30 tons or more from chain hoists . General quality of large-tonnage heavy chain hoists , is not as easy to imagine carrying the general weight of large tonnage chain hoists are about three or four hundred kilograms, the same large tonnage should help large chain hoists lifting frame . So its not as troublesome to install electric hoist. On large tonnage chain hoists prices , the large tonnage of chain hoists expensive. Domestic chain hoist 30 tons to about forty or fifty thousand , one hundred tons of domestic prices in chain hoists three hundred thousand or so, if the imported brand chain hoists prices to over one million . One can imagine a large tonnage chain hoists are also very expensive , the average small business is also rarely used , so large tonnage chain hoists sales have been not very good. View Details

Chain is also called the fairy gourd, jin is not a single girder to use, easy to carry the manual hoisting machinery, also calls the "chain". It is suitable for small short lifting equipment and goods, the weight is jack rack generally not more than 100 t. Lifting chain weight, ye begin moving chain, hand wheel clockwise rotation, the friction slice ratchet wheel, brake pressure into one common rotation, short and long axis rotation piece of gear, the tooth axis and the spline gear. In this way, the device on the spline gear of lifting chain wheel drives the lifting chain, so as to smoothly promote the weight. Drop counterclockwise pulled to pull the chain, brake with the brake pads separation, ratchet in under the action of static pawl, five teeth long axis lifting chain run in the opposite direction, so as to smooth down the weight. Chain generally adopts chip unidirectional ratchet friction brake, can self braking under load, ratchet in under the action of the small electric hoist and ratchet gearing, the brake safety work. Explosion-proof hand chain hoist is a kind of easy to use, easy to carry the manual hoisting machinery, tension is small, weight is lighter, easy to carry, beautiful appearance, small size, durable. Explosion-proof chain in aluminium bronze, beryllium bronze as blank, chain blocks with H62 copper alloy shell material, high-temperature heat treatment so as to achieve the gear according to its rotary gear has high wear resistance.
